怎样调用DataGridViewCellEventArgs事件中的变量
dataGridView1_CellContentClick事件

C# code

        public void dataGridView1_CellContentClick(object sender, DataGridViewCellEventArgs e)        {            string str_class;            str_class = dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex].Value.ToString();            count++;            this.cdTableAdapter.Adapter.SelectCommand.CommandText = "select name from cd where type=\"" + str_type + "\" and class=\"" + str_class + "\" order by code desc";            this.cdTableAdapter.Fill(this.memuDataSet.cd);            if (Rowcnt == 0)            {                this.cdTableAdapter.Adapter.SelectCommand.CommandText = "select name from cd where type=\"" + str_type + "\" and s_men=\"" + str_class + "\" or class=\"" + str_class + "\" order by code desc";                this.cdTableAdapter.Fill(this.memuDataSet.cd);            }                    }

我想在事件外调用调用str_class，目的是为了实现

C# code

        private void 删除ToolStripMenuItem_Click(object sender, EventArgs e)        {            this.cdTableAdapter.Adapter.UpdateCommand.CommandText = "update cd set type=\"DEL\" where name=\"" + str_class + "\"";        }

部分变量

C# code

        public int Rowcnt         {            get             {                return dataGridView1.RowCount;            }        }        public int count=0;         private string n        {            get            {                if (TB=="XF")                switch (count)                { case 1: return "B";                   case 2: return "C";                  case 3: return "D";                  case 4: return "E";                  case 5: return "F";                  case 6: return "G";                  default: return "A";                }                else                    switch (count)                    {                        case 1: return "A";                        case 2: return "B";                        case 3: return "C";                        case 4: return "D";                        case 5: return "E";                        case 6: return "F";                        default: return "";                    }            }        }        public string str_type        {            get            {                if (Rowcnt == 0)                    return "节目";                else                    if (TB == "ST")                        if (count == 0)                            return "SYS";                return "菜单" + n;            }          }

[解决办法]
在窗体类中，增加一个属性

C# code

public class FrmMain {   //   private string _str_class=string.Empty;   public string StrClass  {set{_str_class=value;}get{return _str_class;}  } public void dataGridView1_CellContentClick(object sender, DataGridViewCellEventArgs e)        {            string str_class;            str_class = dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex].Value.ToString();            count++;            this.cdTableAdapter.Adapter.SelectCommand.CommandText = "select name from cd where type=\"" + str_type + "\" and class=\"" + str_class + "\" order by code desc";            this.cdTableAdapter.Fill(this.memuDataSet.cd);            if (Rowcnt == 0)            {                this.cdTableAdapter.Adapter.SelectCommand.CommandText = "select name from cd where type=\"" + str_type + "\" and s_men=\"" + str_class + "\" or class=\"" + str_class + "\" order by code desc";                this.cdTableAdapter.Fill(this.memuDataSet.cd);            }            this.StrClass=str_class; //这样就行了，//当然简单一点的直接定义成窗体类里面的私有变量也行        } private void 删除ToolStripMenuItem_Click(object sender, EventArgs e)        {            this.cdTableAdapter.Adapter.UpdateCommand.CommandText = "update cd set type=\"DEL\" where name=\"" + this.StrClass + "\"";        }
